Law firm bookkeeping cost is driven by scope and condition, not attorney count alone. Two firms with the same number of lawyers can require very different work when one has current operating books and the other has active trust accounts, multiple entities, unreconciled history, or several integrated systems.
Bookkeeping For Law Firms currently lists ongoing bookkeeping from $1,497 per month. Trust work, higher volume, multiple entities, cleanup, and custom reporting are scoped after review. That starting point is useful only when the proposal states exactly what is included.
The factors that change bookkeeping cost
- Account count: operating, savings, credit cards, loans, merchant clearing, and trust accounts each add reconciliation work.
- Transaction volume: the number and complexity of deposits, expenses, transfers, settlements, and case-cost entries affect review time.
- Trust activity: individual ledgers, source records, three-way reconciliation, and exception review require a separate controlled workflow.
- Historical condition: unreconciled periods, duplicate integrations, or unsupported opening balances generally require cleanup before recurring work.
- Entities and ownership: multiple entities, partner activity, intercompany transfers, and different reporting needs expand the close.
- Systems: practice-management, payment, payroll, bank-feed, and accounting integrations require ownership and duplicate controls.
- Reporting: standard statements cost less to produce than custom matter, practice-area, budget, cash, or partner reporting.
- Response process: slow or incomplete source delivery creates follow-up and delays that should be addressed in the engagement design.

- Open-item summary
Trust

- Exception reporting
Repair
Cleanup and catch-up
A project phase for unreliable opening balances or overdue periods.
- Diagnostic review
- Historical reconciliation
- Documented corrections
- Close-out summary
What a useful proposal should state
- Entities, accounts, systems, and periods included
- Whether trust and client-ledger work is included
- Required source documents and delivery deadlines
- Monthly reports and expected delivery timing
- Responsibility for approvals, coding questions, and unresolved items
- Tax-professional coordination, payroll, billing, payables, or other exclusions
- Cleanup assumptions and treatment of out-of-scope history
- Pricing triggers for added accounts, volume, entities, or custom reporting
How to compare two quotes
Normalize the scopes before comparing the prices. A lower quote may exclude trust reconciliation, client ledgers, cleanup, or monthly review. A higher quote may include work the firm does not need. Ask each provider to describe the monthly deliverable, the source records required, who reviews exceptions, and what happens when the books do not reconcile.
Questions to ask before choosing a service
- Which law-firm systems and account types are included?
- Who owns trust decisions and who prepares the records?
- Will every account be reconciled to an outside statement?
- How are duplicate integrations and prior-period changes controlled?
- What reports arrive each month and when?
- What is excluded or priced separately?
- How will the firm and its tax professional receive the workpapers?
Frequently asked questions
Why is IOLTA bookkeeping usually scoped separately?
It adds client-level records, source-document requirements, reconciliation procedures, exception review, and attorney-controlled oversight beyond the operating close.
Is cleanup included in the monthly price?
Not unless the proposal says so. Cleanup should identify the affected accounts and periods, preserve prior reports, and describe how corrections and unresolved items will be documented.
What information is needed for a price estimate?
Expect questions about entities, bank and card accounts, trust accounts and ledger count, monthly transaction volume, systems, last reliable reconciliation, reporting needs, and source-document availability.
Review the current law firm bookkeeping pricing approach, monthly bookkeeping scope, and cleanup process before requesting a proposal.
